Low-temperature plasma air purifiers are products that effectively improve air cleanliness and are mainly divided into household, commercial, industrial and building uses.
Plasma in low-temperature plasma air purifiers is an aggregated substance. It is different from the three-state substances of "solid", "liquid" and "gas" in common sense. It is the fourth state of matter. It possesses high-energy electrons. When it collides with molecules in the air, a series of elementary physical and chemical reactions will occur, and a variety of active free radicals and ecological oxygen will be produced during the reaction, that is, atomic oxygen produced by the decomposition of ozone.
The principle of low-temperature plasma air purifier to remove pollutants:
Under the action of an external electric field, a large number of energy-carrying electrons generated by dielectric discharge bombard pollutant molecules, causing them to ionize, dissociate and excite, and then trigger a series of complex physical and chemical reactions, turning complex macromolecule pollutants into Simple small molecule safe substances can transform toxic and harmful substances into non-toxic and harmless or low-toxic and low-harm substances, so that pollutants can be degraded and removed. Because the average energy of the electrons generated after ionization is 10ev, proper control of reaction conditions can make chemical reactions that are generally difficult or very slow become very fast.

Low temperature plasma air purifier is suitable for
Low-temperature plasma air purifiers are used in home, medical, and industrial fields. In the home field, stand-alone household air purifiers are the mainstream products in the market. The main function is to remove particulate matter in the air, including allergens, indoor PM2.5, etc. It can also solve the problem of volatile organic compound air pollution in indoor, underground spaces and cars caused by decoration or other reasons. Since the release of air pollutants in relatively closed spaces is characterized by persistence and uncertainty, the use of air purifiers to purify indoor air is one of the internationally recognized methods of improving indoor air quality.

Selection of low-temperature plasma air purifiers
1. Filtration technology
The main particulate pollutant filtration technology is HEPA filters. The quality of HEPA filters varies. Although some small brands of filters have high filtration efficiency, they have high resistance, low energy efficiency, are easily blocked, and have a short lifespan. , it is generally recommended to use a deep dust-holding HEPA filter with electrostatic electret. The electrostatic electret technology makes the non-woven fibers have positive and negative charges, which can effectively capture particles in the air. Many HEPA filters claim to have electrostatic electret technology. , but due to technical reasons, the electret charge of many filters will decay quickly in a short period of time, resulting in a reduction in filtration efficiency.
You can choose HEPA filters on the market such as 3M electrostatic electret, which uses the same electrostatic electret technology as 3M masks to ensure that the electret efficiency does not decay for a long time.
2. Pay attention to the applicable area or particulate matter clean air volume (CADR)
The purification ability of an air purifier is mainly determined by the applicable area and the amount of particulate clean air (CADR: the rate of clean air provided). The relationship between the two is: applicable area = CADR × 0.1. The purification ability of other pollutants should be combined with the applicable area.
3. Energy efficiency ratio and energy efficiency grade
Air purifiers are usually used continuously for a long time. As an important indicator to measure the purification capacity and power consumption of air purifiers, energy efficiency ratio deserves everyone's attention. The higher the energy efficiency ratio and energy efficiency level, the more energy-saving the air purifier is and the lower the cost of use.
4. Ozone release amount
As a strong oxidant, ozone has certain purification capabilities, but it is harmful to the human body. The state has mandatory safety requirements for the ozone release amount of air purifiers, which is limited to ≤5×10-6% (ozone has a fishy smell).
